I have an iPhone 8 with a 80% battery, my bad
but
been using a book reader app while at lunch or lite rail commute.
Given I keep the romance novel local to my iPhone (turn off wifi). Results are the battery consumption is way low.
 
For the moment, my work tasks at home are pretty mindless, so I’ll have my iPad Pro 10.5” set up next to my laptop and just have YouTube pretty much running the whole time.

If I’m done work, I’ll usually switch over to my 15” MBP for the bigger screen and better aspect ratio, even though a lot of times it’s still YouTube, lol.

Phone is reserved for sometimes watching short clips before bed, or if I’m on the subway and it’s the only thing I got.
